KataGo's 30% Blunder: G4 Instead of K12 at Move 93

Black was leading comfortably when a single reading error changed everything. At move 93, Black chose G4 — a move that looked solid but missed the critical point at K12. The win rate plummeted from 58% to 28% in one move. KataGo's analysis reveals the correct sequence: K12, then N16, G4, H4 — a patient buildup that maintains the advantage. Instead, G4 gave White the opening needed to fight back and eventually force resignation. Watch as we break down why this seemingly reasonable move was actually a tactical blind spot that cost Black the game. #KataGo #Go #Baduk #Weiqi #GoAI #AIvsAI 章节 / Chapters: 00:00 Opening 03:16 Move 56 · key moment 04:15 Move 65 · key moment 05:40 Move 78 · key moment 07:04 Move 89 · position estimate 07:30 Move 93 · key moment 09:02 Move 95 · key moment 10:24 Move 104 · game decided
